Gravity: Analog pH Sensor/Meter Kit V2 - analog pH meter

Description

Set with a measuring module and a probe to measure the pH of a solution and reflect its acidity or alkalinity. The measurement module has a built-in voltage stabilizer that supports a voltage range of 3.3 to 5.5 V (compatible with 5 V and 3.3 V signals). The analog output signal is hardware filtered. The library supports the two-point calibration method and can automatically identify two standard buffer solutions (4.0 and 7.0). Thanks to the BNC connector of the probe and the Gravity connector, the set can be easily connected to the microcontroller and quickly create a measuring station. It will be perfect for projects involving environmental water quality testing. The user manual and sample programs are available on the Wiki page.
